Description:

TECHNICAL FIELD

The present invention relates generally to an apparatus that circumferentially encases an article with compressive force to be able to axially grip the article, thus providing an axial stop on the article for a selectively axial manual grip on the article by a user. More specifically, the present invention relates to the field of base baseball bat use, in what is termed “choking up” on the baseball bat via placing the players manual grasping of the baseball bat as against the compression collar apparatus to selectively control the baseball bat swinging rotational moment determined from the moment arm distance from the baseball bat centroid or center of gravity to the compression collar apparatus axial position that determines the baseball bat swing force and control.

BACKGROUND OF INVENTION

The practice of gripping a baseball bat at a selected distance from its small or butt knob end portion is termed “choking up”, being a common practice among baseball players. The desire for the so-called “choking up” is primarily for having improved swing control that can be obtained with a heavier and broader bat. In essence, when a batter “chokes up” they grip the bat closer to its centroid or center of gravity, when this is done the moment arm distance between with where a batter grips the bat and the centroid of the bat is a smaller distance as compared to if they bat were gripped adjacent to the small or butt knob end of the bat, the end result of this is that due to the shorter distance moment arm the bat swinging force is reduced thus resulting in reduced muscular stress for the batter and facilitating a more controlled swing by the batter. Further, “choking up” helps prevent wrist twisting by the batter as the follow-through near the end of the bat swing has less momentum due to the shorter moment arm distance. A further use of “choking up” for the batter is to effectuate the practice of “bunting” the ball from a pitch, which is a controlled minimal swing contact with the baseball that useful in certain situations to advance the players on the bases. In addition, for articles other than baseball bats, for instance such as an industrial broom handle, or hockey stick, or other like items, a compression collar apparatus can work much the same way and that it provides a selectable axial stop upon the article for the user to grasp against. Further, for the axial stop which also has the benefit of allowing for a less compressive and less fatiguing hand grip by the user, as the user does not have to grip the article as firmly to help prevent axial movement of the article within the user's hands.

Wherein the key difficulties are in making the compression collar apparatus easily removably engagable to the article while the same time providing a secure axial stop upon the article for manual grasping, plus given the wide variance in article sizes for the compression collar apparatus to deal with. The articles come in a wide variety of sizes which may or may not necessarily be circumferentially round meaning they could be rectangular, square, elliptical, semicircular, and the like, thus further in measuring in a dimension perpendicular to an article longitudinal axis, the article can have this dimension varying, in other words the article can have a taper being similar to a frustroconical shape, all of which complicates designing for a secure and easy removable engagement of the compression collar apparatus to the article, while the same time providing a secure axial stop upon the article for a user to place their manual grasping against. Ideally, the compression collar apparatus provides a mechanism to accommodate the customization of the use of the article in providing a selectable gripping point that is optimum for that particular user.

In looking at the prior art in this area, in U.S. Pat. No. 7,169,069 to Dalton, et al., disclosed is an adjustable collar for attachment around a handle such as the handle of a baseball bat. The adjustable collar in Dalton has a rubber-like strip which has a strap affixed to its outer face. The strap in Dalton extends past the rubber strip and has a ring at one end and a free end at the other end. The rubber-like strip in Dalton is pressed against the place on the handle where it is desired to be attached and the free end is passed through the ring and is looped back toward the free end and affixed to the strap by a hook and loop fastener or other removably engagable fastening structure. Thus, Dalton essentially uses a flexible cloth hook and loop fastener to pull the collar tight about the baseball bat, resulting in a somewhat weaker collar compression about the bat that is not necessarily easily removably engagable.

Continuing in the prior art, in looking at U.S. Pat. No. 6,243,924 to Washburn, Jr., disclosed is an artificial bat end device for temporarily adjusting the length of a bat by using an adjustable ring having a thickness sufficient to simulate the butt end of a bat with the ring, also having the capability to conform to the handle of a bat and be forcibly held in place on the bat's handle. In Washburn Jr., again a hook and loop fastener is used having the same disadvantages as Dalton with the weak retention and non-easily removably engagable attachment, as indicated in FIG. 1, with multiple collars used to move the axial stop away from the butt end of the bat, as the collars brace as against one another and ultimately against the butt end of the bat for the manual grasping by the user.

Next, in the prior art in U.S. Pat. No. 3,469,839 to Pietronuto, et al., disclosed an adjustable bat choke having the characteristics of a bat end comprising a strong flexible body, including a central opening adapted to fit around a bat handle, a cleavage line providing a discontinuity in the bat choke extending through the bat choke's length, a knob portion at one end of said bat choke adapted to simulate a bat knob, and a gripping means adapted to maintain the bat choke on the bat handle at optionally selected positions. In Pietronuto, the gripping means includes a spring confined internally within the body of the flexible bat choke, wherein the bat choke internal diameter also has a high friction surface to help grip the bat, however, the bat choke depending upon the taper of the bat to give the bat choke added frictional gripping power, as the bat choke is a single annular piece flexible shaped element.

Further, in the prior art in United States Patent Application Publication Number 2001/0031674 to McGinnis disclosed is a Baseball Bat Choke-Up Device which includes a C-shaped ring with a hollow center cavity that runs longitudinally through the device. The C-shaped ring in McGinnis has both interior and exterior wall surfaces, wherein the interior wall surface encircles and engages the handle portion of a baseball bat. The C-shaped ring in McGinnis can be separated longitudinally, allowing the Baseball Bat Choke-Up Device to be placed tightly into the desired position around the handle portion of a baseball bat. The C-shaped ring in McGinnis may be secured firmly in place with a hook and loop-type fastener which extends from one side of the longitudinal split to the other, however, having similar problems as previously discussed in Dalton and Washburn Jr., all as having the weak retention and non-easily removably engagable attachment of a hook and loop fastener.

Continuing, in the prior art, for U.S. Pat. No. 5,624,114 to Kelsey disclosed is a resiliently compressible and stretchable sleeve has an opening at one end that is adapted to closely fit around a handle of a baseball bat, and an interior adapted to closely fit around an enlarged end knob which terminates at the handle. The sleeve in Kelsey is positioned to cover the end knob to cushion the batter's hand from vibrations in the end knob and the sleeve can be readily removed from and replaced on the bat. One or more Kelsey sleeves, each having a hole extending completely through it, can be positioned on the handle of the bat to provide a reference for gripping the handle away from the end knob. Thus, Kelsey is a lot like Washburn Jr., in using multiple axially stackable collars as against the butt knob end of the baseball bat to achieve the desired axial stop point for the “choke up” point, with each individual sleeve having minimal axial grip as against the baseball bat via utilizing the butt knob end of the baseball bat as the ultimate axial stop for all of the multiple sleeves.

What is needed is an adjustable article choke constructed partially of flexible material wherein the adjustable choke is easily removably engagable to a variety of article or bat sizes, wherein the adjustable choke or as termed compression collar apparatus securely axially grips the article or bat to provide a firm axial stop for the manual grasping of the article by the user.

SUMMARY OF INVENTION

Broadly, the present invention is a compression collar apparatus for providing compressive force upon an article or for providing an axial manual grasping stop upon the article along an axial longitudinal axis of the article, the compression collar apparatus includes a first arcuate element having a first arcuate axis, the first arcuate element having a first proximal portion and an opposing first distal portion, the first distal portion including an engagement segment that has a plurality of engagement points disposed along the first arcuate axis. Further included in the compression collar apparatus is a second arcuate element having a second arcuate axis, the second arcuate element having a second proximal portion and an opposing second distal portion, the first proximal portion and the second proximal portion have a first pivotal connection to one another about a first pivotal axis for a first pivotal movement, wherein the first pivotal axis and the longitudinal axis are substantially parallel to one another, wherein the first pivotal movement is positioned in a plane that is substantially perpendicular to the first pivotal axis.

An open operational state for the compression collar apparatus is defined as the first and second arcuate elements being moved apart from one another about the first pivotal axis to be able to clear the article and a closed operational state is defined as the first and second arcuate elements being moved toward one another about the first pivotal axis to cause a compressive force upon the article. The closed state is initially effectuated by variably manually compressing the first and second arcuate elements toward one another as against the article via the first pivotal movement to cause the compressive force upon the article, wherein the first and second arcuate elements can be in the closed state at a variable distance apart from one another to accommodate different size articles.

Further included for the compression collar apparatus is a flexible retention arch beam having a free arched state with a free arched axis, a de-arched state with a de-arched state axis, and an intermediate arched state with an intermediate arched state axis, the flexible retention arch beam having a flexible retention arch beam proximal portion and an opposing flexible retention arch beam distal portion, the flexible retention arch beam proximal portion and the second distal portion have a second pivotal connection to one another about a second pivotal axis for a second pivotal movement, wherein the second pivotal axis and the first pivotal axis are substantially parallel to one another. The flexible retention arch beam distal portion having an adjustable interlocking section that has a plurality of interlocking points along the intermediate arched state axis, resulting in a variable removable engagement with the engagement segment forming an interlock as between the flexible retention arch beam and the first arcuate element.

The interlock places the first and second arcuate elements into the closed state, wherein the flexible retention arch beam is in the intermediate arched state, when the first and second arcuate elements are in the closed state about the article, thus putting the first and second arcuate elements in place to cause the compressive force via the flexible retention arch beam that is trying to achieve its free arched state by pulling the second pivotal connection toward the interlock. The de-arched state is effectuated by manually compressibly grasping as between the flexible retention arch beam and grasping by being adjacent to the first pivotal connection to cause the flexible retention arch beam to go from the free arched state to the de-arched state to facilitate the interlock to occur, at which point the manual compressible grasp is released. At this point the flexible retention arch beam progresses to the intermediate arched state to cause the compression force upon the article from the first and second arcuate elements in the closed state.

These and other objects of the present invention will become more readily appreciated and understood from a consideration of the following detailed description of the exemplary embodiments of the present invention when taken together with the accompanying drawings, in which;

The compression collar apparatus 50 includes a first arcuate element 95 having a first arcuate axis 100, the first arcuate element 95 having a first proximal portion 105 and an opposing first distal portion 110, the first distal portion 110 including an engagement segment 111 that has a plurality of engagement points 112 disposed along the first arcuate axis 100, as best shown in FIGS. 5 and 7. Further included in the compression collar apparatus 50 is a second arcuate element 115 having a second arcuate axis 120, the second arcuate element 115 having a second proximal portion 125 and an opposing second distal portion 130, the first proximal portion 105 and the second proximal portion 125 have a first pivotal connection 145 to one another about a first pivotal axis 150 for a first pivotal movement 155, wherein the first pivotal axis 150 and the longitudinal axis 65 are substantially parallel 160 to one another, wherein the first pivotal movement 155 is positioned in a plane 165 that is substantially perpendicular 170 to the first pivotal axis 150, see FIGS. 1 through 6 and 16.

Referring to FIGS. 2, 6, and 16, the open operational state 175 for the compression collar apparatus 50 is defined as the first 95 and second 115 arcuate elements being moved apart 180 from one another about the first pivotal axis 150 to be able to clear 80 the article 55 and a closed operational state 185 is defined as the first 95 and second 115 arcuate elements being moved toward 155 one another about the first pivotal axis 150 to cause a compressive force 70 upon the article 55, as best seen in FIG. 13. The closed state 185 is initially effectuated by variably manually compressing 510 the first 95 and second 115 arcuate elements toward one another as against the article 55 via the first pivotal movement 155 to cause the compressive force 70 upon the article 55, wherein the first 95 and second 115 arcuate elements can be in the closed state 185 at a variable distance apart 200 from one another to accommodate different size 60 articles 55, see FIGS. 3 and 4.

Looking at particular to FIGS. 8 through 11, further included for the compression collar 50 is a flexible retention arch beam 205 having a free arched state 210 with a free arched axis 215, a de-arched state 220 with a de-arched state axis 225, and an intermediate arched state 230 with an intermediate arched state axis 235, the flexible retention arch beam 205 having a flexible retention arch beam 205 proximal portion 240 and an opposing flexible retention arch beam 205 distal portion 245. The flexible retention arch beam 205 proximal portion 240 and the second distal portion 130 have a second pivotal connection 260 to one another about a second pivotal axis 265 for a second pivotal movement 270, wherein the second pivotal axis 265 and the first pivotal axis 150 are substantially parallel 280 to one another, see FIG. 2. The flexible retention arch beam 205 distal portion 245 having an adjustable interlocking section 285 that has a plurality of interlocking points 290 along the intermediate arched state axis 235, resulting in a variable removable engagement 295 with the engagement segment 111 forming an interlock 300 as between the flexible retention arch beam 205 and the first arcuate element 95, see FIGS. 7 and 8.

The interlock 300 places the first 95 and second 115 arcuate elements into the closed state 185, wherein the flexible retention arch beam 205 is in the intermediate arched state 230, when the first 95 and 115 second arcuate elements are in the closed state 185 about the article 55, thus putting the first 95 and 115 second arcuate elements in place to cause the compressive force 70 via the flexible retention arch beam 205 that is trying to achieve its free arched state 210 by pulling 305 the second pivotal connection 260 toward the interlock 300, see FIG. 5 in particular and FIGS. 1, 3, 4, 13, 14, and 15. The de-arched state 220 is effectuated by manually compressibly 515 grasping as between the flexible retention arch beam 205 and grasping by being adjacent to the first pivotal connection 145 to cause the flexible retention arch beam 205 to go from the free arched 210 state to the de-arched state 220 to facilitate the interlock 300 to occur, at which point the manual compressible grasp 515 is released and thereafter manual compression 510 is released, see FIG. 13 in particular. At this point the flexible retention arch beam 205 progresses to the intermediate arched state 230 to cause the compression force 70 upon the article 55 from the first 95 and second 115 arcuate elements in the closed state 185 as originating from pulling force 305 as shown in FIG. 5.

Alternatively, on the compression collar apparatus 50 relating to the flexible retention arch beam 205 distal portion 245 can further include a structural finger depression 255 positioned adjacent to the adjustable interlocking section 285, see FIGS. 2, 3, 5, and 6. Wherein operationally by manually inserting 520 a finger 505 into the structural finger depression 255 and pushing 525 the finger 505 away from the interlock 300 to cause the flexible retention arch beam 205 to go to the de-arched state 220 from the intermediate arched state 230, thus going to the free arched state 210 when disengaging the interlock 300, thus releasing the pulling force 305 to allow the first 95 and second 115 arcuate elements to go from the closed state 185 to the open state 175 and releasing the compressive force 70 on the article 55, see FIGS. 3, 5, 6, and 16.

Optionally, on the compression collar apparatus 50 relating to the engagement segment 105, which can have a serrated ratchet toothed segment 310 having an arcuate pitch line 315 that is substantially parallel 320 to the first arcuate axis 100, see in particular FIG. 7 and also FIGS. 2, 5, 6, 12, and 16. Continuing, for the compression collar apparatus 50 on the serrated ratchet toothed segment 310, it can be formed from a plurality of teeth 325 that each have an equal arcuate pitch distance 330 to one another, a minor diameter 331 segment root angle 335 that is greater that a major diameter 332 segment tip angle 340, resulting in a short distance tooth flank 345 from the minor diameter 331 segment to the major diameter 332 segment and a long distance tooth flank 350 from the minor diameter 331 segment to the major diameter 332 segment for each tooth 325, see FIG. 7 in particular and also FIGS. 2, 5, 6, and 16. Preferably, the pitch distance 330 is about 0.90 inches, and the tip angle 340 is preferably about 41 degrees, and the preferred distance as between the minor diameter 331 and the major diameter 332 on a radial basis, being the tooth 325 depth is about 0.80 inches, as shown in FIG. 7.

Further, on the compression collar apparatus 50, relating to the adjustable interlocking section 285 is preferably a serrated toothed rack 355 having a pitch line 360 that is substantially linear, wherein the serrated toothed rack 355 pitch line 360 forming a tangential relationship 365 with the arcuate pitch line 315 at the interlock 300, see FIG. 5 in particular, and FIGS. 2, 4, 6, 8, 9 through 13, and 16. Continuing, on the compression collar apparatus 50 wherein optionally the serrated toothed rack 355 is formed from a plurality of teeth 370 that each have an equal pitch distance 380 to one another and an equal whole depth 405 as measured from the tooth tip 385 to the tooth root 390, and an angle 420 as between each tooth flank 410 that progressively increases for each tooth 370 in going from adjacent to the flexible retention arch beam 205 proximal portion 240 to the flexible retention arch beam 205 distal end portion 245, see FIG. 8. This resulting in each tooth 370 having a short dimension tooth flank 425 from a root pitch line 395 to a tip pitch line 400 and a long dimension tooth flank 430 from a root pitch line 395 to a tip pitch line 400, wherein each of the short 425 and long 430 dimensions of the tooth flanks 410 both progressively increase in length-from root 390 to tip 385, for each tooth 370 in going from adjacent to the flexible retention arch beam 205 proximal portion 240 to the flexible retention arch beam 205 distal end portion 245, again see FIG. 8. The interlock 300 is defined as a removably engagable contact 435 as between a single short distance tooth flank 345 and a single short dimension tooth flank 425, the progressively increasing long dimension tooth flanks 430 structurally accommodate an increasing projected length 440 of the long tooth flank distance 350 due to the first pivotal movement 155 of the first 95 and second 115 arcuate elements moving apart 180 from one another to facilitate a larger size 60 article 55, see FIGS. 5 and 12 in particular and FIGS. 2, 6, and 16.

Thus, the variable length tooth flanks 425, 430 act as a Vernier type scale, i.e. by having unequal teeth 370 sizing that accommodates alignment of the single short distance tooth flank 345 and a single short dimension tooth flank 425 forming the interlock 300, wherein for various size 60 articles 55, the particular teeth 325, 370 that form the interlock 300 are different. Further, as the first arcuate element 95 moves 155 toward a more open state 175 (this accommodating larger size 60 articles 55) the projection distance 440 increases, wherein the projection 440 is projected as against the pitch line 360, see FIGS. 5 and 12, requiring that the eventual mating flank 425 be angled as between root 390 and tip 385 to better match the mating flank 345 angle as between root diameter 331 and tip diameter 332 to form the interlock 300. Plus this coupled with the flexibility of the retention arch beam 205 that during the compression force 515 from the finger 505, see FIG. 13, flexes the beam 205 from the free arched state 210 to the de-arched state 220, see FIGS. 9, 10, and 11 to move the tooth tips 385 to better facilitate tooth flank 425 to grab tooth flank 345 to form the interlock 300 at variable positions of the first arcuate element 95 from movement 155 to ultimately accommodate various sizes 60 of the article 55.

Looking toward FIG. 8, preferably, for the angle 420 as between each tooth flank 410 that progressively increases for each tooth 370 in going from adjacent to the flexible retention arch beam 205 proximal portion 240 to the flexible retention arch beam 205 distal end portion 245 the angles 420 progress from about 41 degrees to about 50 degrees. In addition, preferably for each of the short 425 and long 430 dimensions of the tooth flanks 410 both progressively increase for each tooth 370 in going from adjacent to the flexible retention arch beam 205 proximal portion 240 to the flexible retention arch beam 205 distal end portion 245, the increase in the short dimension 425 and the increase in the long dimension 430 are controlled by the tooth tips 385 being equidistant to one another as defined in the equal pitch distance 380 of about 0.08 inch and as the angle 420 increases and the equal whole depth 405 being preferably about 0.08 inches stays consistent, the tooth roots 390 shift in relation to the tooth tips 385 in the same direction as the increasing angles 420, thus the shift going from the proximal portion 240 toward the distal portion 245 resulting in increases in the short dimension 425 and increases in the long dimension 430 as between the tip 385 and root 390, as only the first short dimension tooth flank 425 that is closest to the proximal end portion 240 is positioned perpendicular to the pitch line 360, as shown in FIG. 8.

Additionally, referring to FIGS. 5, 9, 10, 11, and 13 for the compression collar apparatus 50 relating to the flexible retention arch beam 205, that has a flexing stiffness for movement 305 as between the free arched state 210, the intermediate arched state 230, and the de-arched state 220. Wherein the stiffness is measured in a plane 275 that is defined via the second pivotal movement 270 as between the second pivotal axis 265 and the adjustable interlocking section 285 with the stiffness being preferably in the range of about 1,000 pounds per inch to ultimately create the compressive force 70 while the flexible retention arch beam 205 is in the intermediate arched state 230. The stiffness of the flexible retention arch beam 205 is best shown by the manual compression 515 via the finger 505 that acts as against the interlock 30 and the second pivotal connection 260, as best seen in FIGS. 5 and 13 resulting in the three states of the free arched state 210, the intermediate arched state 230, and the de-arched state 220. Note that the preferred stiffness of about 1,000 pounds per inch could be more or less depending upon materials of construction for the flexible retention arch beam 205.

Continuing, on the compression collar apparatus 50, wherein the flexible retention arch beam 205 is preferably constructed of nylon or a suitable equivalent to accommodate the desired transitions from the free arched state 210, to the intermediate arched state 230, and to the de-arched state 220. Also as an option, for the compression collar apparatus 50 related to the first 95 and second 115 arcuate elements each can further include an inner surface 135 wherein is disposed an elastomeric rib 140 that is intersticed as between the inner surface 135 and the article 55 when the first 95 and second 115 arcuate elements are in the closed state 185, being operational to further enhance the grip or frictional contact from the compressive force 70 upon the article 55 from the first 95 and second 115 arcuate elements in the closed state 185 to ultimately strengthen the axial stop 75, see FIGS. 3, 4, 13, 14, and 15.

METHOD OF USE

Referring specifically to FIGS. 2, 4, 5, 6, 13 through 16, for a method of using a compression collar apparatus 50 comprising the following steps of firstly providing the article 55 having a longitudinal axis 65, the article 55 can also be in the form of a baseball bat 85 with its own longitudinal axis 90 or any other article 55 that could be applicable that could use the compression collar apparatus 50 that can potentially provide an axial stop 75, this would include but not be limited to broom handles, hockey sticks, golf clubs, Lacrosse sticks, pole vaults, or medical uses such as limbs, and the like. A next step of providing the compression collar apparatus 50 as previously described, see FIGS. 1 through 6.

Further, a step of compressing manually 510 with fingers 505 with a selected compression force in a variable distance manner 200 the first 95 and second 115 arcuate elements toward 70 one another 195 as against the article 55 via the first pivotal movement 155, wherein the first 95 and second 115 arcuate elements can be in the closed state 185 at a variable distance 200 apart from one another to accommodate different size 60 articles 55, further continuing the step of compressing manually 510 through the following step, see in particular FIGS. 3, 4, and 13.

Next, a step of grasping manually 515 with fingers 505 in a compressive manner as between the flexible retention arch beam 205 and being adjacent to the first pivotal connection 145 to cause the flexible retention arch beam 205 to go from the free arched state 210 to the de-arched state 220 to facilitate the interlock 300 to occur, see FIGS. 3, 4, 5, and 13, while notably still retaining compression force 510 as delineated above. Subsequently a next step of releasing the manual compressible grasp 510, wherein the flexible retention arch beam 205 progresses from the de-arched state 220 to the intermediate arched state 230, thus placing the compression collar 50 in the closed state 185 with a compression force 70 on the article 55 originating from the pulling force 305 that ultimately translates into the compressive force 70, see FIGS. 5 and 13.

Moving onward, an optional step for the method of using the compression collar apparatus 50 can further comprise a step of inserting manually 520 a finger 505 into the structural finger depression 255 and pushing 525 the finger 505 away from the interlock 300 to cause the flexible retention arch beam 205 to go to from the de-arched state 220 from the intermediate arched state 230, thus going to the free arched state 210 when disengaging the interlock 300 to allow the first 95 and second 115 arcuate elements to go from the closed state 185 to the open state 175, and releasing the compressive force 70 on the article 55 allowing the compression collar 50 to be removed or cleared 175 from the article 55, see FIGS. 2, 3, 5, 6, and 16.
